Yes 2x3i5x & BC_Programmer, that is exactly what I have experienced & thank you both for your input.
I can see a new wave of my friends asking me just exactly the same questions, showing equally as much confusion. ( Have I been out of the loop so long that I dont know these things anymore.)
BC_Programmer has the knowledge of the disappearing restore points. So indeed 2x3i5x, I have already made a new set of restore points & am happy with the equipment ( well as happy as one can be given different variables.)
I do make the occasional "Backup" to an external drive BC_Programmer & 2x3i5x, however I just wonder these days how relevant these are now. Usually once a year...ish on a 2 TB, might be room for just one more. Maybe I should format that drive & start again.
2x3i5x, I'll go through the links you supplied & make sure I can reset the laptop to something I am used to or am happy to use.
Many thanks. ImnoGuru.
